There are plenty of places in the Midwest. The problem is you wouldn't want to live in those neighborhoods.
I cannot argue with your assessment if any exist. Here in KC, we are the last of the cities with a metropolitan area of two-million plus to experience urban renewal. Which means anything decrepid is being ripped to shreds. Let alone the fact that real estate prices have declined less than five percent. Therefore, other than the ghetto (say Linwood and Prospect), a $75,000-99,9999 home will not exist.
